Not OP, but we are using Tyk (tyk.io) at my workplace. It's definitely more user friendly than Kong, but we've had other issues with it. Having not used Kong extensively but knowing what it is, I'll go out on a limb and say Kong is likely more performant.
Actually it should be the opposite. Definitely do your own benchmark, but take a look at the latest numbers from Tyk and compare it with the latest numbers from Kong to get a general idea.
This analysis was done by BBVA comparing Tyk and Kong performance https://www.bbva.com/en/api-gateways-kong-vs-tyk/ - disclosure: I work for Kong, but Kong (the company) had no involvement with the benchmarking in that article.
Those BBVA benchmarks look very very wrong. BBVA achieved 3822 requests per second with a 16Gb server running Tyk.
I used a 16Gb Digital Ocean box, and a separate box to run benchmarks from.
Tyk CE with keyless api.

As per above results, I got 25,244 requests per second. 90% of requests were served with sub 15ms latency.
Another thing - you can freely scale with Tyk CE as much as you want at no-cost. I currently run 3 gateways in prod and it doesn't cost a penny. The BBVA article states that you need to pay Tyk to scale - simply not true:
>However, if we want to deploy a significantly larger number of microservices, or simply ensure high-tolerance to failure, we need to scale up the number of gateways. In the case of Kong, all it takes is adding a new node and connecting it to the database. With Tyk we can do the same, although it will require us to pay for the service. This could be a determining factor when choosing what API Gateway to use.
I went through process picking API gateway about 3 months ago. Tyk is not without it's warts, but has far more out-of-box features baked in (inc distributed rate limiting) than Kong. And if custom plugins are required, I can choose between lua, python, js or anything that supports gRPC. With Kong - stuck with Lua.... no thank you.
I guess my point here is that if Tyk not performant enough for you, just add another gateway. And if I need custom functionality - I don't need to learn Lua.
Hey Bob - you'll be pleased to hear Tyk took that feedback on-board. There is now very comprehensive documentation and user-guides. And true to the Open Source approach, anyone can contribute to them, the community have been great in working to improve them.
